rib to clench the staple. f

In order to provide ample roomfor the manipulation of the shoe and forthe operation of the pincers or grippers 30, the stapley formingmechanism (which will hereinafter be described in detail) is soconstructed and arranged as to form a staple in a location outofalinement with the staple driver 36 and above the path of movement ofthe dri-ver., The machine is provided with means for transferring thestaple downwardly into alinement with the-.driver ybetween' successivestaple forming and driving operations. For forming the staple there isprovided an inside former 38 supported on a stationary bracket 40secured to the head of themachine by a 'cap screw. 4 2. The remainder ofthe staple forming mechanism and the .means for transferring the staplefrom forming position to driving position with the exception Aof theWire. cutting means are carried by a .slide 44 which also carriesl thestaple guiding nozzle34, this slide being mounted for reciprocating'-movement in aninclined guideway in the head of the machine. The slideis moved along its guideway through connectionsV to a cam which isclearly described in the Letters Patent above referred to. f Y

Attached toa stationary'bracket 39 secured to' the head of the machinein adjustable relation to the inside former 331s a wire guiding tube 46,

Vto which wire is fed by a pairof feed rollers (not guide member 48. Thetop of the guide 'meme -ber 48 and the lower portions of the U-shapedmembers 50, 52 form a slot or recess through which the wire passes andwhich positions the wire in proper relation .to wire cutting means.

The nozzle 34 is secured in position on the member 48 by means of a setscrew `54 which holds the nozzle 34 against movement relatively to themember 48. The upper end ofthe member48 is shaped to preventinterference with the stationary parts of the staple cutting andformingV mechanism. Mounted on a block 55 secured to the stationarybracket 39 by a stud 57 in front of the wire guiding tube 46 is a wirecutting knife '56 which is provided with an inclined cutting edge 58.Cooperating with theknife 5S is a movable cutting knife 60, secured to ablock 4'! attached tothe slide 44 by a stud 49 whichr operatesA tosevera length of wire, the cut being formed ata `substantial angle orobliquely tothe longitudinal axis of thewire. nThe-'otherr end of, thesevered lengthof--wirefiscut by agpair ofknives 62, 64 at an angleinclined vina directionv opposite tothe angle at which the first end ofthe length is- Lacasse cut. The member B2 is attached to the stationarybracket 39 by a stud 4| and is provided with a cutting edge 58inclined'in a direction opposite to the inclination of the cutting edge58 on the knife 5B. The member 64, which co-operates with the knife 62,is mounted on the slide 44 and is movablewiththe cutting member 60. Thelength of Wire is cut with the beveled ends inclined downwardly andtoward each other.

The knives 68,64., above referred to, are mounted on an upward"extension ofthe nozzle 34 rearwardly of the vmember 48 and prior to thewire severingo'peration are located just rearwardly The inner surfacesof the members 60,-64 are provided with a pair of members or outsideformers 68 which cooperate with the inside former 38 to form the lengthof wire into a staple. The members 68 are "spaced apart a distancesuiiicient to clear the inside former 38. After the staple has beenformed,it is in a position to be transferred to the driver passage 70 inthe nozzle 34. The staple l2 after it has been formed is moveddownwardly into the driver passage l0 in the nozzle 34 by' downwardmovement of the outside former 68 in the manner described in LettersPatent No. 1,795,451 above referred to.

VAt the same time that the'staple 12 is being; formed the nozzle 34,also secured to the slide: '44, is vbeing moved toward the shoe. ,Theupper U Vof the shoe inthe meantimehas been gripped Vby the pincers 38.1The lasting pincers are then given an upward ymovement to tension theupperand when thelasting pincersill have moved in wardly to lay theupper over an insole S the nozzle 34 engages the upper to lay the upperoverv the marginof the .in sole.Y During these operations, the anvil 3 2which also acts as a shoe rest, engages the vinner edge of the rib Rthereby resistingtthe pull of the pincers and actingv asr a gage orguide for the work. The operation a -of the lasting pincers 30 and thestaple inserting instrumentalities described just above is substantlallythe same as in the Letters Patent abovementioned to which referencemaybe had for a more complete description of the construction andoperationof these parts.

The legs of the staple 'l2-are provided with ends 13 beveled insubstantially the same plane. When the staple 'l2 is transferred to thedriver passage i0 in the nozzle 34 the staple is in asubstantially'horizontal 1 position with the beveled portion ofthestaple legs lowermost. When the staple l2 is driven into the work, thevstaple be- -cause ofthe beveled ends tends to follow an upwardly curvedpath in the work. The bevel, however, is suiiiciently great to'preventthe staple from curling in the work but when the end of the staplestrikes the anvil'32 the legs are turned upwardly and back into the workto secure the staple inthe work. By turning the staplev upwardly in thismanner the rib R is made more rigid and consequently will not bedistorted or displaced'as readily as when the legs of the staple areclenched in some other manner.

VHaving thus described the invention, what is claimedias new Yanddesired to be secured by Letters Patent of the United States is:
